This example demonstration various orientations for vertical bar meters.<br><br>
In a vertical bar meter, the scale labels can be positioned on the left or right side of the meter scale. This is controlled by the last argument to <a href="LinearMeter.setMeter.htm">LinearMeter.setMeter</a>, which can be <a href="Chart.Left.htm">Left</a> or <a href="Chart.Right.htm">Right</a>. The color scale can also be position on the same or opposite side as the scale labels.
